What does HVAC stand for?

HVAC means heating, ventilation and air conditioning. We frequently use this phrase to refer to your complete heating and cooling setup, which involves:

  • Comfort equipment, such as a furnace, heat pump, air conditioner or mini-split system
  • Ductwork
  • Indoor air quality solutions, like air filters, air filtration systems, germicidal UV lights, whole-house humidifiers and dehumidifiers, and ventilation
  • Comfort controls, like thermostats systems

While there are different models of HVAC units, they all operate similarly by:

  • Pulling from a fresh air source outside or inside your residence or business.
  • Moving air through a filter to get rid of dirt and allergens.
  • Heating or cooling air.
  • Sending air using a ducted system or immediately into a area, depending on the model of system you use.
